Taxonomic note: On pl. 3, fig. 19 of "Sammlung europäischer Schmetterlinge", Hübner (1796) figures Tinea mediella. Since a long time, this taxon is treated as a junior subjective synonym of Tinea choragella [Denis & Schiffermüller], 1775 (= Morophaga choragella). Hübner´s figure however clearly shows the species, which is known as "tessulatellus" since Zeller (1846), a fact that has already been supposed by Zeller itself (Zeller 1846: 182). Therefore, Tinea mediella Hübner, 1796 has to be treated as senior subjective synonym of Euplocamus tessulatellus Zeller, 1846, having priority over the younger name. Nevertheless, it should be considered to suggest Euplocamus tessulatellus as nomen conservandum to the ICZN, since it has been in use since many decades.

Description of adults (Hannemann 1977): Forewing length: 11 - 14 mm. Vestiture of hair-like scales on the head pale yellowish; forewings pale ochreous-yellow with brown dots and fascia-like spots; distad to middle of costa a big brown spot, elongated to an indistinctly bordered fascia to inner margin, variable in width; a distinct blackish spot on discal crossvein; hindwings light grey.

Distribution:

M. tessulatellus is recorded from Karsholt & Nieukerken (2011) only from Scandinavia, the Baltic states, Poland, Slovakia and Sicily, although it is distributed most probably in large parts of Europe. Dubatolov (2011) records the species also from the west Siberian plain. The vertical distribution is documented from apr. 300 - 1500 m a.s.l. (Kurz & Kurz 2011), Hannemann (1977) records it for medial and high altitudes.

Nearly no data are available about the biotope preferences of the species. Hannemann (1977) records it from young forest plantations with decaying stumps of spruce and beech. Imagines have been found from May to August on clear cuttings, but were also found at light in settlements (Kurz & Kurz 2011). The animals fly around sunset (Hannemann 1977).

Stages in development:

Larva. Following Petersen (1957), the larva lives in wood-fungi and in rotten wood.

Genitalia (Petersen 1957). Uncus bilobed, each lobe crowned with saw tooth, which are increasing in size towards middle; the two largest teeth lie crosswise; valvae comparatively simple, but joined medially by the anellus; aedeagus short, broad, everted vesica with numerous small teeth.

Genitalia (Petersen 1957). Subgenital plate not extended into humps; ostium broad, flat; apophyses normal; ductus bursae broad, proximal part heavily sclerotized; signa not traceable.

The species is very similar to Morophaga choragella ([Denis & Schiffermüller], 1775), but is best distinguished by the blackish spot on the discal crossvein. Male and female genitalia of both species are very different from each other.
